Adding new decks

Decks are stored as .rds files in inst/extdata/decks; all with the standard naming format deck_KEYWORD.rds. Internally, when a deck is identified by name (e.g. bechara), iowa searches for the filename using

system.file(paste0('extdata/decks/deck_', deck, '.rds'), package = "iowa")

And so as long as the deck is given a unique identifier, is named appropriately, and is placed in the appropriate directory, it should be available to all functions within the package (e.g. simulateIGT()) when the package is recompiled.

Note that this may be convenient if an alternative deck structure is used frequently, but all relevant functions also accept custom deck structures as list objects (see the relevant article).
